Why should you choose this mattress?
Choice here comes down to brand reassurance and convenience. Silentnight is a long established British manufacturer, and the boxed format makes getting the mattress into your home far simpler than wrestling a flat one up the stairs. It's available in four sizes, UK Single, Double, King and Super King, so most bed frames are covered. The price range sits in mid-market territory, though we can't yet weigh that against a detailed spec.

FAQ's
How much does the Silentnight Just Sleep Calm Mirapocket 1000 cost?
It depends on the size you choose, and the price table on this page shows the current price for each size.
What sizes does the Calm Mirapocket 1000 come in?
It's available in four UK sizes: Single, Double, King and Super King. That covers most standard British bed frames, though always measure your frame before ordering.

Yes. It arrives rolled and vacuum-packed in a box, which means it's much easier to manoeuvre through hallways and up stairs than a traditional flat-delivered mattress. It expands once unpacked.
